Aim: To examine efficacy of polychemotherapy (PCT) CHOP-21 in patients with diffuse large B-cell lymphosarcoma (DLBCL).
Material And Methods: Fifty-five DLBCL patients received first-line therapy according to CHOP-21 program in 1996-2004. The diagnosis was made by WHO criteria.
Results: Initially, 37 patients had lymph node lesions, 18--nonlymphatic lesions. Complete remissions were achieved in 49% (56.7% in nodal lesions, 33.3% in extranodal ones). Overall 5-year survival was 35%, event-free--25%, for patients with nodal lesions--36 and 32%, respectively, extranodal lesions--35 and 22%, respectively. Overall 5-year and event-free survival in patients with local lesions was 85 and 75%, generalized--25 and 20%, respectively. In patients with involvement of the gastrointestinal tract 3-year overall and event-free survival reached 50 and 45%. Event-free survival was not seen in patients with extranodal lesions of other locations in overall 3-year survival 45%.
Conclusion: PCT program CHOP-21 was effective in DLBCL patients with local nodular lesions except cases with large-size tumors, invasion in the adjacent organs and tissues and isolated gastric lesion.

Radiosurgery versus radiation therapy for long term local control rate of craniopharyngioma: a meta-analysis.

Introduction: Craniopharyngiomas are challenging benign tumors arising from Rathke's pouch remnants, often requiring multidisciplinary management due to their proximity to critical neurovascular structures. This meta-analysis systematically compares conventional radiation therapy (RT) and stereotactic radiosurgery (RS) in treating residual or recurrent craniopharyngiomas.
Method: A comprehensive literature search identified 44 studies, including 46 reports, meeting inclusion criteria such as progression-free survival (PFS) and post-radiotherapy complications.

Aims: Fluid accumulation is associated with poor outcomes in patients with heart failure (HF). After acute HF, HF nurses provide home care suggestions based on oedema status assessed at outpatient clinics. However, the pattern of serial oedema changes and their associations with patient outcomes are unknown.

Introduction: Corticosteroids are used for toxicity management, raising concerns about whether they may affect the anti-leukemic effects of chimeric antigen receptor (CAR)-T cells.
Methods And Results: In this study, we retrospectively analyzed patients (fined two subgroups based on disease burden. Of the 75 cases in the low disease burden (LDB) group (MRD < 5%, no extramedullary disease), there was no significant difference between the use of steroids and event-free survival (EFS) ( = 0.

Background: Improving the intraoperative and postoperative performance of laparoscopic hepatectomy was quite a challenge for liver surgeons.
Aim: To determine the benefits of indocyanine green (ICG) fluorescence imaging in patients with hepatocellular carcinoma (HCC) who underwent laparoscopic hepatectomy during and after surgery.
Methods: We retrospectively collected the clinicopathological data of 107 patients who successfully underwent laparoscopic hepatectomy at Zhongshan Hospital (Xiamen), Fudan University from June 2022 to June 2023.
